Summary
👤
Senior🎓
Top SchoolLewis Metcalf is a pragmatic software engineer and founder with eight years’ experience building developer tooling, distributed systems, and great developer experiences. He’s co-founded Amp Code after roles at Sourcegraph and Auth0 where he improved platform resiliency to “four nines,” expanded CLIs and CI/CD workflows, and shipped container orchestration tools to speed local development. Comfortable across Go, Node/TypeScript, and cloud-native stacks, he combines TDD, RFC-driven design, and asynchronous remote-first practices to deliver reliable, maintainable systems. Earlier stints at ThoughtWorks and his own startups show a knack for turning product concepts into production-grade services and UX-informed admin tools. Based in York, England, he favors simplicity and learning-by-doing—evident in hands-on writeups like his from-scratch regex series—and mentors colleagues while scaling platform reliability.
